This document describes a study that evaluated a one-day interdisciplinary project called the Robot Love Design-a-thon for preservice teachers. The project brought together preservice teachers from arts, sciences, and primary education to solve complex problems in interdisciplinary teams using a design process. Observations and student reports found that the condensed one-day format facilitated exchange of ideas and critical discussions on the socially engaged theme. Students also reported that working in interdisciplinary teams allowed them to benefit from each other's expertise, which emerged as an important learning outcome. The document provides background on how design-a-thons and interdisciplinary ArtsSciences education can help develop 21st century skills and prepare students for solving complex societal challenges.
